Abstract In order to consider the influence of soil moisture content change on slope stability Hejin Cherry Valley Garden Project, this paper firstly selects samples at typical locations obtain shear strength test results loess under different content; Then, based rhinoceros and FLAC3D software, reduction method is used analyze stability, impact water comprehensively evaluated according safety ...

Today, the most urgent problem of existing and future nuclear power industry is to ensure environmental safety operation reactor units (NPPs) plants (NPPs). It solved thanks application deeply echeloned protection an anti-accident complex methods means for effective control active zones (AZR). However, danger NPPs in world from time manifests itself form severe post-project accidents catastroph...

a brief background to the development of the rock engineering design process is given, showing that since the development of the science of mathematics, deterministic methods have been used to perform various calculations. the variability of rock properties and support characteristics have always been known. however, they were not explicitly used in design but compensated for by the use of a sa...

The subventricular zone (SVZ) is a source of neural progenitors throughout brain development. The identification and purification of these progenitors and the analysis of their lineage potential are fundamental issues for future brain repair therapies. We demonstrate that early postnatal NG2-expressing (NG2+) progenitor cells located in the SVZ self-renew in vitro and display phenotypic feature...

Dilemma Zone Design as a Marginal Cost-Benefit Problem" (2007). One control objective at high-speed isolated intersections is to provide safe phase transition by minimizing the occurrence of high-speed vehicles in the dilemma zone before the phase is terminated. An upper limit for extending the green (maximum green time) is used to avoid an indefinite extension of the main-street green. Current...

Roadside vegetation provides numerous environmental and psychological benefits to drivers. Previous studies have shown that natural landscapes can effectively lower crash rates and cause less stress and frustration to the driver. However, runoff the road crashes resulting in a collision with a tree are twice as likely to result in a fatality, thus reinforcing the need to examine the placement o...

While sophisticated analytical methods like Morgenstern-Price or finite elementmethods are available for more realistic analysis of stability of slopes, assessment of the exactvalues of soil parameters is practically impossible. Uncertainty in the soil parameters arisesfrom two different sources: scatter in data and systematic error inherent in the estimate of soilproperties. Hence, stability o...

The production of meat from sheep and goats in Australia occurs almost entirely at pasture in zones known as the semi-arid pastoral zone, the wheat-sheep zone (where sheep and crops form an agricultural rotation system) and the high rainfall zone. Each zone has particular factors which affect the human health hazards associated with sheep and goat meat and the opportunities for prevention. The ...

A series of specified domains in Nu-Mu interaction diagram are proposed to determine optimal reinforcement schemes for rectangular RC column sections subjected to uniaxial eccentric load. These domains divide the area covered by interaction diagram into four regions of safety zone, compression-controlled zone, balanced failure zone and tensioncontrolled zone, which can help engineer to understa...
